Hive 处理敏感字段 字符串替换

使用regexp_replace格式:

regexp_replace(address,"正则表达式","替代字符")


(1)匹配所有字符:

select regexp_replace(address, '.*', '***') from table;


(2)匹配指定字符:

select regexp_replace('2016-06-05', '-', '') from table;


(3)匹配特殊字符(换行符):

select regexp_replace(name,'\\\\n','') from table;

 

例子:

SELECT  concat(SUBSTR(user_log_acct, 1, 6), '*****') AS user_log_acct  -- 只保留前六位,后面脱敏

SELECT  regexp_replace(scene, '@@', '_') AS scene  -- 替换指定的字符串
